What Ω means
Ω is the ohm symbol, used for electrical resistance. You will see it in values such as 10 Ω, 220 Ω, or 4.7 kΩ. It is common in electronics, physics, repair notes, and product specifications.
Copy-paste for accuracy
Because Ω can be confused with the Greek omega in some contexts, copying the correct symbol is often safest. Use consistent spacing, such as 10 Ω, especially in technical documents.

Keep formulas readable
the symbol is helpful in homework, spreadsheets, lab notes, engineering comments, and short formulas. If the audience may not know the symbol, write the word once first and then use the symbol after that. This keeps the content accurate without slowing the reader down.
Copy symbols carefully between apps
Math and science symbols can change appearance depending on the font. After pasting the symbol, check spacing, superscripts, and surrounding numbers. In plain text fields, avoid using an image of the symbol because it will not search, copy, or scale as well.
